Had a real scary situation yesterday but could of been alot worse. I will give you the short version. Stopped at a F/Jays to get fuel in Kentucky before we got into the mtns. noticed my rear tire was not in line with the front tire on the coach. Had to spend the night in a parking lot and wait for customer service to open in the morning. There was a RV dealership that sold some Heartland products 2 doors down. Called Matt and he got the dealership to expedite the repair, we are on our way south for the winter. The tech who worked on the coach said the center pin on the spring sheared off because the u bolts were not torqued to spec. This could of been a fatal accident if I was going 60 miles an hour in the mountains. So please everyone find out the torque for the u bolts and put that on your list of things to do before you leave on a trip. Don't mean to scare anybody but wanted to share this with you all. Gotta give thanks to Jim B for settleing me down during this tramatic experiance, a big thanks to Matt for expediting the repairs and thanks to the guys at Delightful Days RV center in Walton, KY for making the repairs in a timely manner and thanks to God for keeping us safe. Thank yous are not necessarly in order.
Four of mine were loose when I discovered the bent center hanger. The proper torque is on the spec sheet that you can down load. Would give it but I think everyone should take a look at the sheet. Most RV folks carry a torque wrench as they should for the camper wheel lugs as well as the TV. Thanks to another post we discovered our problem prior to taking off on a trip. Wound up replacing the axles to get a little margin for safety.

Well guys, ask me about an axle coming loose. 5% downgrade at 60mph. As told to me by the guy that replaced my springs, the torque is 65#. I am beginning to think that the "U" bolts stretch and the nuts come loose. I did put "locK-tite" on the threads. So we will see if the nuts come loose or the "U" bolts stretch. I would check them at least once a month. Bob
The critical measurement is to torque all 4 bolts evenly up until the plate starts to deform slightly. Max torque on grade 5 1/2 inch bolts is 92 pounds. The plate will bend prior to reaching that. The torque should the the same on each bolt and the same on each side. Never have <50 pounds even if the plate deforms quite a bit.
Torque U bolts
What are the factory torque settings for the U bolts on the axle and spings of a 09 Bighorn 3670? I am planning a cross country trip next summer and do not want any major problems. My friend lost his axles in Ohio this past summer for the same reason.
Thanks

I've been to Heartland & Lippert's websites. Could you post the page web address please?
TIA
I'm unable to find that spec sheet you suggested.

In the website listed below I found a torque specification table under their FAQ tab. Also, there was other information about springs and axles that I found quite interesting.

Looks like the U-Bolt torque is missing. All the other data is there. 65 pounds seems to be the range when the plate starts bending. Attached is the general brochure with the equalizer and hanger torque settings. However you dont want to tighten them so they dont have room to freely move as designed so it is a judgment call.

Wish I had known about this before. It may have saved me a $1200.00 bill! Why don't they advise of this the same way they do for wheel lugs. A little more caring and communication would be nice.
